EFFECT OF CIS-TRANS ISOMERISM ON THE UREA INCLUSION COMPOUND FORMING-ABILITY OF A MOLECULE; A STUDY OF THE MALEATE-FUMARATE SYSTEM

摘要

Several maleates and fumarates were investigated to determine their ability to form urea inclusion compounds. Olefinic esters of both acids will form inclusion compounds. However, the shortest chain required to stabilize a particular ester was related to the over-all cross-sectional diameter of the ester. The fumarates, having the more slender conformation form complexes more readily than the maleates.
